class not found exception

[sam liya]

I am getting class not found exception in my sms receiver class.

below is my receiver class

package com.androidexmple.broadcastreceiver;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.telephony.SmsMessage;
import android.util.Log;
import android.widget.Toast;

public class IncomingSms extends BroadcastReceiver {

	// Get the object of SmsManager
	final SmsManager sms = SmsManager.getDefault();

	public void onReceive(Context context, Intent intent) {

		// Retrieves a map of extended data from the intent.
		final Bundle bundle = intent.getExtras();

		try {

			if (bundle != null) {

				final Object[] pdusObj = (Object[]) bundle.get("pdus");

				for (int i = 0; i < pdusObj.length; i++) {

					SmsMessage currentMessage = SmsMessage
							.createFromPdu((byte[]) pdusObj[i]);
					String phoneNumber = currentMessage
							.getDisplayOriginatingAddress();

					String senderNum = phoneNumber;
					String message = currentMessage.getDisplayMessageBody();

					Log.i("SmsReceiver", "senderNum: " + senderNum
							+ "; message: " + message);

					// Show Alert
					int duration = Toast.LENGTH_LONG;
					Toast toast = Toast.makeText(context, "senderNum: "
							+ senderNum + ", message: " + message, duration);
					toast.show();

				} // end for loop
			} // bundle is null

		} catch (Exception e) {
			Log.e("SmsReceiver", "Exception smsReceiver" + e);

		}
	}

}

Android is correct - you don't have that class. You do have some other class that you apparently think should be used, but which isn't, because it's not "com.androidexample.broadcastreceiver.IncomingSms". Programming is all about paying attention to details.
